' SPRAYING DEVICE.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed May 31,1904. Serial No- 210,602.

zen of the United States, residing at Seattle,

in the county of King and State of Washington, have invented certain newand useful Improvements in Spraying Devices, of which the following is aspecification, reference being had therein to the accompanying drawlugs.

This invention relates to a new and improved apparatus for combiningsoap, fertilizing, insecticide, or other compounds with water andfinally discharging the mixture as spray or acompact stream, asrequired.

The object of my invention is to provide a which is automatic in itsaction without the use of valves and free from unnecessary complicationsin its structure.

The construction and advantages of the invention will be hereinafterexplained, and

illustrated in the accompanying drawings, in

which Figure 1 is a sectional elevation of apparatus embodying myinvention, and Fig. 2 is a similar enlarged viewof certain details showntherein.

The reference-letter a designates the end portion of a watering-hoseprovided with a union coupling-nut b, and c is a nozzle which may beprovided with controlling devices(not shown) for regulating and causingit tov discharge the conducted water as a spray or an unbroken stream.Inserted in the line between the parts a and o is a tubular fitting d,having a branch 6, and which for convenience in coupling with adjoiningparts the several ends thereof are provided, preferably, withscrew-threads, as shown. Connected to said branch by a neck f is areceptacle g, preferably globular in shape, which is charged with thesubstances or compounds, which upon being mixed or dissolved with waterforms the spraying solution. Between 'thefouter extremity of the branchand an annular shoulder g interiorly of the receptacle-neck is a disk ordiaphragm h, which is formed or provided with a curved or bentconducting-tube 2', extending downwardly into and having its orificedirected toward or from the hosenozzle 0. This disk is likewise providedwith one or more perforations is, which make communication between saidfitting and the re-' replace substances as forced or drawn therefromthrough the aforesaid conducting-tn when the latter is directed as shownby full lines in Fig. 1, or where it is reversed, asindicated by brokenlines therein, the circulation or flow will be opposite. Gaskets Z and Zmay advantageously be used between the faces of the diaphragm and theopposing surfaces of the said annular shoulder and the end of the branchfor the purpose of preventing any leakage thereat.

In the construction shown the receptacle is charged by removing the sameand filling it through the neck, when, upon being replaced, the deviceis ready to operate, and which is accomplished by the combined action ofthe water in flowing by the protruding end of the conducting-pipe andthe pressure of water to make an unbalanced pressure and create apositive circulation within the receptacle. The amount of the efilux ofsubstances within the receptacle will vary according to the pressure andvelocity of the water and also the direction in which theconducting-tube is dis posed. The device may be used for a great varietyof purposes, such as washing windows with a soap solution, sprayingtrees with a sulfate or other compound, for distributing fertilizer orgreening compounds upon lawns, destroying vermin in chicken-houses withinsecticides, &c., and, as before alluded to, the stream may bedelivered in its most suitable shape by the use of -a hose-nozzle pro-.vided with stream-regulating attachments or by separate nozzles foreach special requirement.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is'

1. In a spraying apparatus, the combination with a water-conduit and anozzle therefor, of a receptacle communicatively connected with thehose, a dud. positioned in said connection and provided with a pluralityof perforations and a conducting-tube carried'by said disk and.projecting into said conduit.

2. In a spraying apparatus, he combination of a tubular fitting having abranch, a receptacle adapted to be secured to said branch, a diskprovided with a plurality of perforations intermediate the fittingandthereceptacle, and a curved conducting-pipe extending from the disk andprojecting into the fitting, said tacle carried by said branch, 3.revolnble disk pipe formed integral with the disk, said disk arrangedbetween the receptacle and the fitbeing provided with a centralperforation ting, acurved conducting-pipe carried by said leading intosaid conducting-pipe and with a disk, the said disk being provided witha pluplurality of perforations lateral of said central 5 rality ofperforations, one of which opens into perforation.
